Huebner Giessen advances magnetic encoder technology
Encoder solutions for large shaft diameters - without bearings and extremely robust
The magnetic scanning principle of Johannes Huebner GmbH uses a stationary sensor that records magnetic field changes of a rotating pulse wheel with north-south poles. The alternating magnetic field produces a sinusoidal or rectangular voltage in this sensor. And the magnetic scanning principle boasts additional benefits: It is resistant to soiling and provides for large radial and axial tolerances. Huebner magnetic encoders are wear-free and low noise. The variant with a split pulse wheel is particularly well suited for retrofitting and upgrading activities as well as for applications without a free shaft end.
Magnetic encoders: Applications and developments
Magnetic encoder technology is used in steel mills, ship drives, gas and water turbines, pumped storage power stations, large excavators in opencast mining, conveyors and drilling rigs, among others. Adjustments can be made to meet the individual customer's requirements. Frank Tscherney, member of the board at Huebner: "Our complete service offering ranges from taking on-site measurements, analysing the installation position and designing the appropriate magnetic encoder system through to production, delivery and on-site assembly. We provide just the services our customer needs."
Magnetic encoders by Johannes Huebner GmbH can even be installed in highly confined spaces due to their very slim design. For shaft diameters between 16 mm and 1,000 mm, the system adapts flexibly to the specific set-up of the customer's application. Various options for attaching the pulse wheel are available depending on the actual design conditions, including screw mounting and hot shrink fitting as well as mounting by means of clamping pieces, clamping plates or tolerance sleeves. Magnetic encoder systems from Johannes Huebner can output various types of electrical signals: sinusoidal, incremental and absolute signals (SSI, EtherCat, other bus interfaces).
